Web - Client

I’ve been trying this one for a while and I thought that I’d cracked it.

I’ve come up with some code to use in the main page, which doesnt use parenthesis etc. When i submit in the calculation input on the main page it works and sends my cookie to my requestbin.
However when I submit that url on the contact page I dont get anything coming through to my requestbin.

Am I missing something, maybe another step or needing to format my code a different way? Or is it possible the bot in the challenge isnt working?

yeah me too ，
